UltimateDefrag is the fastest defragmenter I have ever seen. It is compact in structure and easy to use. Just click "Start".

Support four different types of incremental disk fragmentation functions, with policy file configuration options, allowing you to optimize the hard disk drive according to file usage to achieve faster access speed.

This software is based on the rule that most users only use 20% files 80% of the time, so most of the contents on your hard disk are dormant most of the time. With the advanced disk defragmentation mode, you can specify which files and folders are rarely used and put them on slower tracks on the drive, so as to prepare a quick access area for the files you use frequently.

UltimateDefrag can selectively and automatically find these files according to their attributes and access dates that meet your criteria. The interface of the software provides a display function, so that you can visually see the contents of the drive and accurately see the location of files and folders on the physical disk.

UltimateDefrag doesn't need you to be an expert, but if you are, you will find a large number of configurable options that allow you to customize the defragmentation process in any way. The software also includes a scheduler, which is used for automatic disk defragmentation operation, and supports disk defragmentation at computer startup and background disk defragmentation.

● Comments: The operation is simple, just click a button. Sorting speed is faster than any software, and disk fragments can be arranged automatically and regularly.

Second, O &；; O defragmentation expert

A disk tool specially developed for NT/2000/XP can be applied to workstations, servers and advanced servers, and supports almost all file systems, including FAT 16, FAT32, NTFS, NTFS5, FS (Encrypted File System) and so on. It is a rare good tool.

The hard disk can be automatically reorganized at the set time, and supports long Chinese file names. Windows NT Service Pack 4 or Windows 2000 must be installed first. The software does not require high hardware environment, 486 computers, at least 16MB memory and VGA graphics card, which I think is easy to meet.

Defrag can only run under Win NT/2000/XP, and when it is installed under Win 98/95, it will prompt an error message: Unsupported operating system. Because Win NT/2000 is a multi-user operating system, you must confirm that you have the right to install software on this operating system before installing software.

● Comments: There are five ways to organize disks, and the effect of optimizing the use of space is the best, but it takes a long time to organize disks.

● Recommended star rating: ★★★★

Third, Diskeeper Pro.

The well-known disk defragmenter "Diskeeper" was originally included in Windows 2000. However, the version is older and has only streamlined functions. If you want to use a newer and more functional version, it is a disk defragmenter that fully supports all versions of Windows and integrates Microsoft Management Console (MMC). Can organize Windows encrypted files and compressed files, and can automatically analyze the disk file system. Whether the disk file system is FAT 16 or NTFS format, it can be organized safely, quickly and with the best performance.

You can choose to completely organize or only organize the available space, which can maintain the continuity of disk files and speed up the efficiency of file access. It has the function of scheduling and sorting disks. You can set a timetable for sorting disks, so that you can do disk maintenance automatically.

● Comments: The function is very rich, and you can arrange to automatically defragment the disk regularly. But the CPU share of this program is very high.

● Recommended star rating: ★★★★★

Fourth, VoptXP.

As an old-fashioned disk defragmenter, VoptXP is popular with computer users. The new version of VoptXP is friendlier in appearance and simpler in operation. Through the "Drive" menu, we can manually select the disk partition to sort, and the sorting process will be displayed in different colors at the bottom of the main window, and the capacity of fragments, available disk space, the number of files and folders, and the files in the temporary file recycle bin will be counted.

● Comments: There are many additional tools and the operation is relatively simple. However, the sorting speed is not satisfactory and the stability of the program itself is not good.

● Recommended star rating: ★★★★

Verb (abbreviation for verb) Defragmenter Professional Edition

Disk Defragmenter The disk defragmenter developed by ABEXO Company is divided into Pro and Pro Plus versions. The biggest difference between Pro Plus version and Pro version is that the former has a cleaning tool, which can clean up online records, temporary files and junk files in the recycle bin, as well as delete page files, hibernate files, run disk scan tools, disable screensavers and other gadgets.

● Comments: The defragmentation speed is fast and the CPU utilization rate is low, but its defragmentation effect is relatively general.

● Recommended star rating: ★★

Six, the perfect disk (VISTA is not supported)

Perfect disk is a product of Raxco company, which has the most common operation interface and function of disk defragmentation software, that is, analyze the disk first and then reorganize it. Both FAT and NTFS formats can accurately analyze hard disk partitions and maintain hard disk continuity. This software advertises under the slogan of faster and better than DiskKeeper! After trial, this program is definitely much better than that VOptXP finishing effect!

You can also reconfigure the hard disk or floppy disk of a remote computer through a network connection. Whether the disk file is in FAT or NTFS format, it can intelligently analyze the disk file format, reorganize files and directories in different sectors of hard disk or floppy disk safely and quickly, maintain the continuity of hard disk or floppy disk files, and access files more efficiently.

● Comments: The layout is concise, and detailed suggestions will be given after software analysis. Coupled with various humanized designs, it is more in line with the usage habits of Chinese people. Simple operation, support network analysis and disk defragmentation, but the speed is a bit slow.

● Recommended star rating: ★★★★★

Seven, a more alternative ghost of defragmentation

If you only use GHOST to back up and restore data, you will be wronged by this "powerful" software. In fact, you can also use Ghost to organize your hard disk. As we all know, when using Ghost as a disk image, Ghost will completely read out every data in the hard disk partition and then write it into a GHO file. The software will automatically skip the blank part of the partition.

Then when we restore the GHO image file, the software will write all the contents of the file into the partition continuously, so that all the data will be automatically written into the partition header, and we will get a complete unused space, and the original fragmented file will naturally disappear.

The specific method of defragmenting with GHOst is to scan and repair all the error codes on the partition, and then create a Gho image file for the partition to be defragmented with Ghost. The size of the file depends on the usage of the partition, and then restore the GHO file to the original partition. These operations are best run in pure DOS mode, and the correct partition must be selected when restoring the image, otherwise the data will be lost.

● Comments: The operation under pure DOS is complicated, which is not suitable for ordinary users who are not familiar with GHOST. Be careful when backing up and restoring, it is easy to cause data loss!
